The problem is that there is a loophole in the formation layout of absorbing aura, so the speed of absorbing aura is greatly reduced.

Cheng Yu carefully studied this part of the formation, like this composite formation, once it was cracked, Cheng Yu felt that his understanding of the formation had reached a new level again.

After spending a day really understanding this formation, Cheng Yu officially began to repair the formation.

Formation repair is actually much more complicated than direct arrangement, but fortunately, although Cheng Yu is not a master of formation, he is quite proficient, and after so many studies and practices, his understanding of formation has become much deeper.

Cheng Yu thought about it, since this formation controls the speed of aura absorption, can he transform this formation?

But after thinking about it, I gave up, because I didn't seem to have this type of formation in my head.

The Spirit Gathering Array is to help gather the aura and suck in the aura around it. And the Soul Locking Array is to lock the aura in the formation and prevent the aura from escaping.

And this spiritual absorption formation is much more advanced than these two formations, it can directly help people absorb spiritual energy, and it can also quickly increase the speed of absorbing spiritual energy, which is amazing. It can be said that this formation is the main formation of the entire Dayan Inheritance Cultivation Array!

However, Cheng Yu still didn't think that this speed was fast enough, and he even wanted to speed it up. Luckily, he couldn't speed things up, otherwise he would have done it.

Although I thought to myself, there was no way to improve it, so I could only repair it according to the original formation. As the main formation of the cultivation array, it was also very time-consuming to repair, and it took Cheng Yu a day and a night to successfully cultivate this formation.

But with the previous example, this time he didn't directly call people to come in to cultivate, but first re-compared his formation with all the contents on the formation map and runes, and after confirming that there was no problem, he was relieved.

"Family Master!" Seeing Cheng Yu come out, the four guards said respectfully.

"Well, you two go and call the disciples of the eighth layer, and then you help them guard for a few days. Cheng Yu thought for a moment and said to two of them.

"Yes! The family master!" The four disciples were a little surprised, the family master was also going to improve their realm!

It's just that they don't understand why the family master suddenly did this, he had raised the realm for the four of them before, and now he has to raise the realm for the disciples of the eighth layer, this family master is also too good, right! Could it be that he plans to raise the realm for all the Cheng family disciples?

After a while, the four guard disciples of the eighth layer came up.

"Family Master, are you looking for us?" Seeing the Family Master, the four disciples asked respectfully.

"Yes, you guys come in with me!" Cheng Yu nodded and entered the ninth floor again.

Like the four disciples before, they also had doubts, but they followed behind Cheng Yu with nervousness and anticipation.

"You work hard for the sake of your family, and in order to reward you, so I am ready to upgrade your realm once!" Cheng Yu looked at the four of them and smiled.

Although Cheng Yu just asked them to do an experiment this time, it was not against their will to say these words, after all, they were really contributing to the Cheng family.

Moreover, the reason why he did this was also for the future of the Cheng family, not to mention, such an experiment was beneficial and harmless, and the four disciples before were a good example.

If the disciples of the Cheng family knew that Cheng Yu was looking for guinea pigs, I believe that all the disciples of Cheng Yu would be happy to do this experiment.

"Thank you for cultivating!" said the four disciples in surprise.

The two guards who called them up before told them that there was a good thing for the four of them, but they didn't expect it to be a good thing.

Cheng Yu didn't say much, just told them what to do, and then activated the formation again.

Although the formation had been repaired by him, it didn't seem to have changed the effect. Therefore, Cheng Yu can only stay outside the formation and wait for the result.

But this time, Cheng Yu really succeeded, and the four of them completed the breakthrough in just one day.

"Congratulations, you are now a monk in the foundation building period, you must work harder to cultivate in the future and reach a higher realm as soon as possible!" Cheng Yu looked at the four of them and said with a smile.

"Thank you, master!" the four of them knelt on the ground and kowtowed to Cheng Yu in surprise.

"Remember, don't tell anyone about this!" Cheng Yu said.

"Yes, we won't leak this out!" the four nodded, anyway, they had already received such a good reward, and of course they didn't want everyone to be like them, all of them were rewarded, so this reward was too inferior.

Seeing that the four of them went out, Cheng Yu checked it again, and felt that he had indeed achieved his goal, so he didn't continue to stay, and he also got out of the cultivation tower.

"Senior brother, you can be regarded as coming out, tell me if I won the gamble last time!" Seeing Cheng Yu come out, Xinhai suddenly rushed out.

"I really admire you, have you really been waiting for me here?" Cheng Yu said speechlessly when he saw these people.

"No, I won't go anywhere without results!"

"Didn't I say it last time, I didn't make any big moves, you lost!" Cheng Yu said.

"I don't believe it, we've already seen it!" Xinhai looked around, and cautiously whispered to Cheng Yu: "Did you arrange that formation this time?"

"What formation? I don't even know what you're talking about?" Cheng Yu shook his head.

"Hmph! You don't pretend to be garlic, that formation is clearly what you have been making up in it during this time! The last time you called those four disciples, it was clearly to let them experiment for you, don't think we don't know anything!"

"Now that you all know, what are you asking me for?" Cheng Yu said helplessly.

In fact, he already knew that these guys had seen some eyebrows, but this was nothing, anyway, everyone had long thought that there was a formation in it.

"We just want to check the results!"

"Okay, you won!" Cheng Yu said as he looked at the other party.

"I knew that the last time you made me miserable, it was clear that I won, but you said I lost. As a result, I ran my sister's leg for half a month in vain. Xinhai said with a depressed face.

"I'm doing this for your own good, think about it. Last time, Senior Brother Xinluo almost missed his marriage because of something in the bar. Isn't it only your little junior sister in your heart? If you go to that kind of place to play, if you get some kind of evil disease, it will be passed on to your little junior sister at that time, won't this make you have a conflict with your little junior sister?" Cheng Yu said with a smile!
